摘要
目的解决受地层岩性、地质构造、水文地质和采矿空区等复杂条件影响下的边坡稳定性监测预警问题.方法以戒台寺古滑坡体为例,基于戒台寺边坡地质条件分析基础,采用边坡监测预警系统对戒台寺滑坡稳定性进行实时监测预警.研究了系统的感知层、传输层、应用层,根据恒阻大变形锚索受力状况证明了古滑坡体下滑力监测的可行性.结果在戒台寺安装的3个边坡稳定性监测预警站点应用结果表明,滑动力相对变化值PV处于动态变化调整之中,30005#、30002#和30004#监测站点PV的最大值分别为10%、14%和7%,没有出现滑动力增量ΔP持续增大或减小且PV大于10%的情况,说明戒台寺滑坡暂时处于稳定模式状态.结论研究成果为类似滑坡监测工程提供了一种可靠、有效、崭新的解决方案.
Problems of slope stability monitoring and early warning, under the influence of complex conditions such as the lithology of construction, geology, hydrogeology and mining area, are needed to be addressed. In the case of Jietai Temple landslide, based on the analysis of slope geological, the slope monitoring and early warning system is designed. The system comprises sensing layer ,transport layer and application layer. The status of constant large deformation resistance cable proves the feasibility of ancient landslide sliding force monitoring. Application results of 3 slope stability monitoring and early warning station installed in Jietai Temple show that：The sliding force＇s relative value（PV）is in the dynamic changes and adjustment. 30005#,30002# and 30004# stations＇ PV maximum values are 10%, 14% and 7% respectively. No sliding force increase（ΔP） continues to increase or decrease and Pv is greater than 10%, which indicates Jietai Temple slope is currently in stable model condition. The research results have provided a reliable, effective and new solution for the similar landslide monitoring project.
